KARL SOHLIEPMANN, OF ST. CHARLES, MISSOURI, ASSIGNOR TO ST. LOUIS OAR COMPANY, OF ST. LOUIS, MISSOURI, A CORPO- RATION.

SASH-BALANCE FOR CAR-WINDOWS.

SPECIFICATION forming part of Letters Patent No. 790,321, dated May 23, 1905. Application fi led January 3, 1905. Serial No. 239,523.

To all whom it may concern.-

Beit known that I, KARL SOHLIEPMANN, a citizen of the United States, residing in St. Charles, in the county of St. Charles and State of Missouri, have invented certain new and useful Improvements in Sash- Balances for Street-Car Windows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a sash-balance for street-cars, the object of the invention being to so mount the balance-drum that it may partake of a swiveling motion to avoid kinking of the metal balance-ribbon in lowering and raising the sash connected thereto, which being set at an angle to a perpendicular line is necessarily first raised at an angle to unseat it from the sash-rail before lowering it into the pocket between the inner and outer panels of the car.

Figure I is a vertical section taken through a portion of the side Wall of a street-car, including a sash and my balance connected thereto. Fig. II is an elevation of the parts shown in Fig. I with portions in vertical section. Fig. III is w an enlarged vertical section taken on line III III, Fig. I. Fig. IV is an enlarged horizontal section taken on line IV IV, Fig. III. Fig. V is an edge view of the drum and hanger of my sash-balance.

A designates the inner panel, and B the outer panel, of astreet-car side wall. Between these panels is a sash-receiving pocket C, that is closed by a trap-door D.

E is a panel-rail surmounting the outer panel.

F is one of the window-posts containing the sash-runway G, that extends upwardly from the sash-pocket O. This sash-run way is wider at its lower end than at its upper end to permit of the sash H being swung outwardly to rest upon the sash-rail E or move inwardly to be lowered into the sash-pocket when the trap-door D is open. 1

1 designates one of a pair of sash-balance ribbons secured at 2, Fig. II, to the sash H. 3 is a drum to which the balance-ribbon 1 is secured and on which it is wound. Passing transversely through the drum 3 is a spindle 4, that is surrounded by a convolute spring 5, one end of which is fixed to said spindle and to the other end of which is fixed said drum at itsinterior.

The sashbalance parts as thus far described are of common form, and no invention per se is herein claimed for such parts.

6 designates a hanger-yoke in the arms of which the spindle 4 of the balance-drum is fitted, said hanger-yoke being provided at its upper ends with pintles 7. I

8 represents brackets secured to a fixed portion I of the car-body and apertured to receive the pintles of the hanger-yoke 6, thereby providing for the swinging'of the hangeryoke to permit sway of the sash-balance drum.

It will be seen that by mounting the sashbalance drum and its hanger so that they may swing thesaid drum is rendered susceptible of moving into direct alinement with the sash 8, to which the balance-ribbon is connected, irrespective of. the positioning of the sash in a vertical line or out of a vertical line. Therefore when the sash is swung outwardly in its uplifted position and resting upon the sashrail the balance ribbon will extend in a straight line from the sash to the balancedrum, and when the sash is raised and moved into perpendicular position to be lowered into the receiving-pocket C the balance-drum will follow the movement, thereby avoiding the occurrence of kinking of the balance-ribbon.

.connected to said drum, a hanger in .which said drum is rotatably mounted, pintles extending from said hanger at its upper ends, and supporting-brackets in which said pintles are loosely fitted, substantially as set forth.

KARL SOHLIEPMANN. In presence of H. F. NOGEL, M. H. MURPHY.
